" Application filed April 17, 1922. Serial No. 558,630.

To all whom it may concern:

Be it known that I, HENRY; J. KINNEY, a citizen of the United States, residing at Indianapolis, in the county .of Marlon and State of Indiana, have invented a new and useful Mathematical Game Apparatus, of which the following is a specification, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon.

This invention relates to the type of game apparatus which includes mechanism intended to be designedly operated in the attainment of the results sought, and the in vention relates more particularly to a mechanism and indicators whereby simple mathematical problems may be worked out in an amusin and instructive manner.

An'o ject of the invention is to-provide a new and useful game apparatus'which shall be so constructed and operated .as to be amusing to children particularly, and to encourage them to learn simple numbers and I est in the new claims.

to add them together.

Another object 1s to provide a new game apparatus which shall be entertaining in character and also puzzling so as to excite interga'me.

A further object is to provide a new game apparatus which shall be educational, not costly to manufacture, which shall be attractive and easily operated and be durable in use.

With the'above mentioned and other objects in view, the invention consists in novel mechanism and indicators whereby mental calculations may 'be indicated and results announced by a signal, and'the invention consists also further in the novel parts, and in the combinations and arrangements of parts, as hereinafter particularly described and further defined 1n the accompanying Referring to the drawings,Figure 1 is a top plan of the new game apparatus; Fig. 2

is a top plan of the internal mechanism of\ the apparatus, the casing of which is uncovered; Fig. 3 is a sectlonal elevatiomapproximately on the line IIIIII in Fig. 2; Fig. 4 is a fragmentary sectional elevation on an enlar ed scale approximately on the line IVI in Fig. 3; Fig. 5 isa fra mentarv section approximately on the line -V in ig; 2 on an enlar ed scale; Fig. 6 is a fragmentary sectiona elevation similar to .Fig. 4.- but having various elements represented as in difi'erent positions to those in the other figure; Fig. 7 is a fragmentary section on an enlarged scale approximately on the line VH--VH in Fig. 2; and, Fig. 8

is a perspective view of one of the pointers comprised in the apparatus.

Similar reference characters in the different figures of the drawings indicate corresponding elements or features of construction herein referred to in detail.

The game apparatus as preferably constructed comprises a casing which incloses parts of the apparatus and has other parts thereof on its top as a game board, the casing comprising a bottom or base 1, side Walls 2 and 3, end walls 4 and 5, and a top or cover 6, all suitably connected together. A suitable frame is rovided and secured within the casing and 1t preferably comprises a base plate 7 arrangedwn the bottoml and having an upright end plate 8 provided on its top with a top bar 9, the base plate having an opposite end plate 10 provided on its top with atop plate 11; and the plate 7 has also two upright side frame members 12 and 13 thereon. A guide bar 14 is secured to the to bar 9 and the to plate 11 and it has upwar 1y extending. si e guides '15 and 16 to which.

top guide lips 17 and 18 are connected respectively. upon the guide bar 14 and it has gear teeth 2O on one of its side edges in proximity to one end thereof. The rack bar may be variously operated and controlled, but preferably by duaLmeans such as a crosshead 21 having longitudinal slots 22and 23 adjacent to its opposite ends respectively, the central portion of the crosshead being connected to the rack bar by means of a suitable ivot 24 v having a head 24'. Two parallel gulde bars 25 and 26 are horizontally arranged at a suitable distance from opposite sides res eotively of the guide bar 14 and are secure at one end to the top bar 9, the opposite end of each guide her being provided with a leg 27 that is secured to the base plate 7 Two operating shafts 28 and 29- are arranged under ,the guide bars respectively and extend through the end wall 4 of the casing, bein rotatablysupported in the end plate 8 an the legs '27, each operatin shaft having screw threads 30 thereon. wo nuts 31 and 32 are arranged on the operating shafts respectively in connection with the screw A rack bar 19 is slidingly guided.

threads thereon and are rovidedwith guide .ing slidingly guided on the guide bars 25 and 26 respectively, each box preferably having a guideway therein through which the uide bar extends. The guide boxes have stud s 36 and 37 fixed thereon respectively that extend upward through the slots 22 and 23 respectively'and also through slots 38 and 39 which are provided in the top 6 of the casing so that one end of the crosshead may be moved by one of theoperating shafts and the opposite end of the crosshead may be moved by the'remaining one of the operatin shafts, the operating shafts being provided respectively with suitable hand wheels 40 and 41. The studs have pointers 42 and 43 secured to the upper portions thereof respectively, each pointer having a squared hole 44 receiving the stud, and they point to a numbered scale or indicator having suitable characters or 1 symbols thereon to which the pointer may be moved. Preferably two similar graduated scales or tables 45 and 46 are provided in any suitable manner upon the top -6 between the slots 38 and 39, one having numerals 47, 48, 49 thereon, the other having similar numerals 47 48', 49.

The numerals on each scale as illustrated are 1 to 10 inclusive arranged in numerical order along the scale. Preferably the top 6 has two ribs 50and 51 arranged adjacent to the scales respectively and having each a series of ten notches 52 in the top thereof at the respective numerals in the scale, to securely hold the pointers when set, and to permit accurate positioning of the pointers, also so that the crosshead and the rack bar shall be brought to proper positions necessary in the operation of the apparatus.

At a suitable position in proximity to the side member 12 the base plate 7 has a shaft 53 rigidly supported thereon that extends upward in proximity to one side of the guide bar 14, and it has a relatively small portion 54 from which extends a relatively smaller portion 55 at the lower end of which is a shoulder 56, and a disc 57 is rotatively arranged on the portion 55 and supported upon the shoulder, the disc having gear teeth 58 on its periphery that mesh with the gear teeth 20 on the rack bar,.there being a gap in the side guide 15 permitting the meshing of the gear teeth. The disc has a socket or hole 59 therein on one side of the axis of rotation of the disc. The top 6 of the casing has an aperture 60 therein through which the shaft portion 55 extends and in which a portion of a yoke 61 is received that is rotatively arranged en the portion 55 of the shaft above the disc. A push-rod 62 is guided for vertical movement in the'yoke 61 so as to be entered in the hole 59 when in register there with, the yoke and the disc being-independently rotatable, and the push-rod has a knob 63 on its topfor convenient operation nevaooa the yoke to constitute a portion thereof and-- to cover the aperture 60, andit has a pointer 67 fixed thereto that extends across a dial 68 suitably fixed upon the top 6. The dial comprises a suitablenumber of numerals 69, 70,

71, arranged in a circle, being numbers 1 to.

20 inclusive as preferably designed to constitute a mathematical apparatus, although in some cases other characters or symbols may be substituted for the numerals to af-' ford an interesting puzzle. The top 6 has a circular rib 72 thereon that is concentric to the stationary shaft and it has notches 73 in its top arranged at the numbers or characters to permit the pointer 67 to be accurately positioned at the diflerent numbers or characters.

Constructed as above described the apparatus may be quietly operated, but in order to render the game a little more interesting an audible signal preferably is provided, and to this enda collar 74 is movably arranged on the shaft portion 54, being provided with a guide sleeve 75, and a rock-shaft 76 is supush-rod upward. A

ported by the frame side members 12-and 13 and has a toothed wheel or segment .77 se-' cured thereto that is provided with a forked arm 78 extending under the collar 74 to be operated on the downward movement of the collar. A spring 79 is Wound about the frame member 13, whereby a signal may be given whenthe push-rod 62 passes through the hole 59in the disc and pushes the collar 74 downward, indicating that the problem or uzzle has been successfully solved.

n practical use, the hole 59 in the disc 57 being invisible,'the object of the player of the game is to bring the push-rod 62 in alignment with the hole and push it into or through the hole, and when the gong is present in the apparatus to further push the push-rod down to the collar 74 and rock-shaft 76 and has its inner end connected v thereto, the outer end of the springbeing operate the collar and to sound a signal on the gon or bell. The bringing of the pushrod, an the hole into alignment is interestingly facilitated by proper setting of the together being navaeea pointers- 'respectively at the corresponding means for operating and controlling the' rack-bar 19, and two pointers and scales are provided as illustrated, either one or both of the shafts 28 and 29 may be rotated to move the pointers 42 and 43 or either of them to any of the numbers desired on the scales. For instance, the pointer a2 may be brought to and set at the number Z, the pointer 43 being brought to and set at the number 3, the sum of 7 and 3 added 10. Or the sum of 10 may be attained by other numbers such as 6 and 4, 8 and 2, and so forth. Having decided upon the value of the total of two numbers, as 10, the ointer 67 is brought .to and set at the num or 10 on the dial 68. Then the push-rod 62 may be depressed into the hole 59 in the disc 57 and may be pushed through the hole to operate the collar 7 whereby the sound signal is operated. Conversely, the

pointer 67 may be set at any one of the numbers on the dial, after which either one or both of the shafts 28 and 29 may be rotated to bring the pointers 42 and 4:3 to a number or numbers on the scale that shall total the number indicated on the dial, after which the push-rod may be successfully operated. When either one or both of the shafts 28 and 29 are operated the crosshead 21 moves the rack bar 15} and it causes rotation of the disc 57. The operation of either one of the shafts 28 and .29 is suiiicient for any number from 1 to 10 inclusive but when a greater number or total is desired the remaining shaft must be operated, assuming that each pointer has a range of 10 positions and that the dial has 20 indicating marks, as illustrated for example.
